Current computing technologies require a constant input of energy \u2013 which is mostly wasted as heat. I am developing nitride magnetic materials that can operate 1000x faster than current computers and have reduced losses, therefore saving energy.<\/p>\n<p><strong>Why do you use the Royce facilities at Imperial for your work?<\/strong><\/p>\n<p style=\"font-weight: 400\">Royce at Imperial is the home of a state-of-the-art kit I couldn\u2019t really access anywhere else, so that was a big motivating factor. Also, getting access to the Royce facilities is straightforward, and nearly everything I need is located in the same area. So, I can grow a sample in the morning and be performing structural and surface analysis on the same sample in the afternoon, without any time wasted!<\/p>\n<p><strong>Which facilities do you use at Royce?<\/strong><\/p>\n<p>Growth facilities (Pulsed Laser Deposition), Atomic Force Microscopy, X-ray Diffraction, Cleanrooms (Ion milling, E-beam lithography) and SPIN-lab \u2013 it is probably easier to list the facilities I don\u2019t use!<\/p>\n<p><strong>In what ways did access to our facilities contribute to your research?<\/strong><\/p>\n<p style=\"font-weight: 400\">It is essential for my research. Using the facilities here has allowed me to develop new processes and new material combinations I have never tried before, with great success.<\/p>\n<p><strong>Has working at the Royce facility led to any new insights or learning experiences?<\/strong><\/p>\n<p style=\"font-weight: 400\">Royce offers a space to interact with other users and find out about their projects. From this, I have had many new opportunities to collaborate and learn new things, which is a massive benefit to me!<\/p>\n<p><em><strong>Royce at Imperial is a hub for start-ups, industry and academia to make, test and characterise materials, components and systems.<\/strong><\/em><\/p>\n<p><em><strong>If you are interested in using the facilities, please visit the <a href=\"https:\/\/www.imperial.ac.uk\/royce-facilities\/\">Royce at Imperial website<\/a>.<\/strong><\/em><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Dr Freya Johnson is a Visiting Researcher in the Department of Physics.
